Three operating room nurses from the hospital also observed the new procedure, a laser laparoscopy. A carbon dioxide laser was used to treat endometriosis, a disease in which the inner lining of the uterus is found outside a woman's uterus.

According to Dr. Listwa, other methods for treating the disease can be quite costly, and traditional surgery requires a five- or six-day hospital stay plus a month of recuperation. With a laser laparoscopy it can be a same day procedure. The patient can go home the same day as the operation and could be back to work in three days.
